Meet Luxembourg's Hereditary Grand Duke Guillaume and Duchess Stéphanie

After a very quiet couple of months on the royal news front, the world has a new baby prince to celebrate.

Luxembourg's Hereditary Grand Duke Guillaume, 38, and Hereditary Grand Duchess Stéphanie, 36, welcomed their first child on Sunday morning.

Charles Jean Philippe Joseph Marie Guillaume's birth was announced on the Grand Ducal Court's official Twitter account.

Luxembourg's royals don't hit the headlines quite as often as their British or European counterparts, so here's what you might not know about the new royal parents.

The heir apparent

Guillaume, 38, is the eldest son of Grand Duke Henri and Grand Duchess Maria Teresa of Luxembourg. He is one of five children: Prince Félix, Prince Louis, Princess Alexandra and Prince Sébastien.

He was educated in Luxembourg and abroad in Switzerland, the UK and France.

In 2000, Guillaume became Luxembourg's heir apparent when his father ascended the throne.

A royal romance

Prince Guillaume had known Countess Stéphanie de Lannoy for years before they began dating.

The daughter of the late Count Philippe de Lannoy and Alix della Faille de Leverghem, she is part of an aristrocratic Belgian family. Stéphanie is the youngest of eight siblings.

Like her now-husband, she studied in various countries including France, and is multilingual.

Guillaume publicly confirmed the news of their relationship in an interview on his 30th birthday in 2011. Their engagement was announced the following year.

The wedding

The couple wed over two days in October 2012. Proceedings began with a civil ceremony, conducted by the mayor of Luxembourg, followed by a larger religious ceremony at Notre-Dame Cathedral the next day.

Stéphanie wore a Elie Saab lace gown, accessorising with the Lannoy family tiara and a 14-foot train, while her groom wore the Luxembourgish military uniform.

Sadly, the bride's mother died just two months before the wedding.

Like the British royal weddings of recent memory, Stéphanie and Guillaume exchanged a public kiss on the balcony of the Grand Ducal Palace after the ceremony.

The event was attended by royals including England's Prince Edward and Sophie, Countess of Wessex; Denmark's Princess Mary and Prince Frederik; Spain's then-Prince Felipe and Princess Letizia; Monaco's Princess Stephanie; and Sweden's Princess Victoria and Prince Daniel.

According to The Luxembourg Times, the couple said ahead of their wedding that they hoped to have a large family.

The statement said members of both families were "delighted with the news" and shared the couple's "great joy". A series of portraits of the expectant parents were also released.

Charles Jean Philippe Joseph Marie Guillaume was born early on Sunday May 10, and will be second in the line of succession to the Luxembourg throne after his father.

He is the fifth grandchild for Grand Duke Henri and Grand Duchess Maria Teresa.

As family members are currently unable to visit maternity wards in Luxembourg due to coronavirus restrictions, the couple met little Charles via video call from Berg Castle.

The official royal Twitter account shared photos of the encounter, writing: "A digital meeting, certainly, but one charged with emotion."

Speaking to media on Sunday, new dad Prince Guillaume described his son's birth as "probably the most incredible day that we will have in our life."

"We are delighted to [share the news] in a time that is a bit more difficult, especially for families that have been separated for a few months," he added.

"A birth is a message of hope, it's a blessing, and I think this is what we are so happy to be able to share."
